Description

Technical Field

[0001] The invention belongs to the technical field of road construction devices, and particularly relates to a cutting device for road construction. Background Art

[0002] Road construction is carried out by staff in combination with modern equipment. When it is necessary to increase the friction of the road surface or repair the damaged road surface, grooving of the road surface is required. The road cutting device can assist workers in construction quickly and smoothly.

[0003] When the traditional road cutting machine cuts the road, a hand-pushed road cutting machine is adopted. It is necessary to draw a line in advance to mark the cutting route and then manually push the cutting machine along the marking for road cutting. It is easy for the cutting machine to have a position deviation during movement. Especially for inclined roads, it is difficult to control the moving direction of the cutting machine, and it is impossible to adjust the position of the cutting tool in time to make it operate perpendicular to the road surface in the face of complex terrain. In addition, the existing road cutting devices generate relatively large noise during operation and it is difficult to clean the mud and dirt generated during the cutting operation in time. Summary of the Invention

[0004] To solve the above-mentioned existing problems, the invention provides a cutting device for road construction, which adopts the pre-action principle combined with an elastic structure. According to the inclination of the road, the position of the cutting tool can be adjusted in time to ensure that the cutting tool is perpendicular to the road, avoid damage to the cutting tool, and improve the adaptability of the cutting device to complex terrain. The cutting tool is cooled and the dust is reduced by spraying water. At the same time, the power motor is water-cooled and shock-absorbed, which not only reduces noise but also prolongs the service life of the power motor. In addition, the mud and dirt generated during the cutting operation are cleaned in time by the water mist recovery mechanism and the water is recycled, improving the working efficiency of the road cutting operation.

[0005] To achieve the above object, the technical solution adopted by the invention is as follows: A cutting device for road construction provided by the invention includes a guiding mechanism, an adjustable power assembly is arranged on the guiding mechanism, a shock-absorbing and cooling cutting assembly is arranged below the adjustable power assembly, and a front baffle mechanism and a water mist recovery mechanism are respectively arranged on the front and rear sides of the shock-absorbing and cooling cutting assembly; the adjustable power assembly includes a driving mechanism arranged on the guiding mechanism, an adjusting mechanism is arranged below the driving mechanism, and a hydraulic telescopic column is arranged below the adjusting mechanism; the shock-absorbing and cooling cutting assembly includes a cutting mechanism, a shock-absorbing power mechanism and a spraying mechanism, the cutting mechanism is arranged at the telescopic end of the hydraulic telescopic column, and the shock-absorbing power mechanism and the spraying mechanism are respectively arranged on both sides of the cutting mechanism.

[0006] Further, the cutting mechanism includes a protective cover, a cutting blade, distance-adjusting telescopic columns, and a mudguard. The protective cover is provided at the lower end of the hydraulic telescopic column. The protective cover is semi-circular. The cutting blade is rotatably provided inside the protective cover.

The clamping plates are circumferentially distributed outside the power motor and are provided inside the power housing. Shock-absorbing springs are evenly distributed between the clamping plates and the inner wall of the power housing, and the power motor is coated with a waterproof coating.

[0008] Further, the spraying mechanism includes a water tank, a first suction pump, a connecting pipe, a second suction pump, and a third suction pump. The water tank is provided on the side of the protective cover away from the power housing. The first suction pump is provided on the power housing. The connecting pipe is connected to the first suction pump. The output end of the first suction pump communicates with the power housing. The connecting pipe penetrates the telescopic end of the hydraulic telescopic column and communicates with the water tank. The second suction pump is provided at the lower end of the water tank. The output ends of the second suction pump and the power housing are respectively communicated with the symmetric water collecting cavities through water pipes. The third suction pump is provided on the side of the water tank close to the water mist recovery mechanism. During use, the power motor drives the cutting blade to rotate. The first suction pump and the second suction pump work. The second suction pump directly sucks the water in the water tank into the water collecting cavity on one side, while the first suction pump sucks the water in the water tank into the power housing through the connecting pipe, and cools the power motor by water cooling when the power motor works. The water flowing through the power housing flows into the water collecting cavity on the other side through the water pipe. The water in the water collecting cavities on both sides of the cutting blade is sprayed out through the water spraying ports, which cools the cutting blade and plays a role in dust reduction at the same time. The heat generated by the power motor during operation is carried away by the flowing water. The clamping plates clamp the power motor, and the vibration generated by the power motor during operation is offset through the shock-absorbing springs. In addition, under the wrapping of the power housing and the water flow, the noise generated by the power motor during operation is difficult to conduct out, playing a role in noise reduction.

The recovery basket faces the cutting knife and is open. The pulleys are symmetrically arranged on both sides of the recovery basket. Preferably, a debris accumulation chamber, an adsorption chamber and a recovery chamber are respectively arranged in the recovery basket. The adsorption chamber and the recovery chamber are respectively arranged on the side of the debris accumulation chamber away from the cutting knife. The recovery chamber is arranged at the lower part of the adsorption chamber. A sludge filter screen is arranged between the adsorption chamber and the debris accumulation chamber. A water leakage net is arranged between the adsorption chamber and the recovery chamber. A suction pipe is connected between the recovery chamber and the third suction pump.

[0010] When the cutting knife is performing road cutting operations, the recovery basket is always close to the ground. The water mist and mud splashed by the cutting knife are sputtered into the recovery basket. Large particle sludge impurities are collected by the debris accumulation chamber. The water mist and the water in the sludge are adsorbed by the first filter cotton through the sludge filter screen. As the cutting operation progresses, the first filter cotton adsorbs more and more water. The conversion motor and the third suction pump are started. The conversion motor rotates the conversion screw column, and then makes the conversion plate slide in the adsorption chamber. The conversion plate slides towards the first filter cotton and squeezes the first filter cotton to squeeze out the water in it. The second filter cotton unfolds under the drive of the conversion plate and continuously adsorbs the water mist sputtered by the cutting knife. The water squeezed out by the first filter cotton falls into the recovery chamber through the water leakage net and is then pumped to the water tank by the third suction pump through the suction pipe for recycling.

[0030] Working principle and workflow: During actual use, the staff arranges the guiding mechanism 1 on the road to be cut. The length of the guiding rod 11 should be selected to be suitable for the length of the road to be cut. At this time, the adjustable power assembly 3 is suspended between the guiding rods 11. Two L-shaped plates are respectively suspended at the connecting plates 13 at both ends of the guiding rod 11 and connected to both ends of the guiding rod 11 to close the driving groove 15 and are fixed with screws if necessary. Subsequently, the main controller is started, and the telescopic length of the hydraulic telescopic column 31 is adjusted to make the first rolling ball 216, the second rolling ball 43, and the pulley 53 touch the ground. The compression spring 6 is compressed, and the distance measuring instrument 7 works. Multiple distance measuring instruments 7 respectively measure the telescopic lengths of the first telescopic column 41, the second telescopic column 51, and the distance-adjusting telescopic column 213. When the distance-adjusting telescopic column 213, the first telescopic column 41, and the second telescopic column 51 are fully extended, the lower end surface of the fender 214 is tangent to the cutting knife 212. Therefore, the relative position of the cutting knife 212 and the ground can be judged by the telescopic lengths of the first telescopic column 41, the second telescopic column 51, and the distance-adjusting telescopic column 213. Multiple difference thresholds of the distance measuring instruments 7 are set in advance. When the first rolling ball 216, the second rolling ball 43, and the pulley 53 touch the ground, if the values of the distance measuring instruments 7 in the first telescopic column 41, the second telescopic column 51, and the distance-adjusting telescopic column 213 are equal or within the difference threshold, it means that the plane formed by the landing points of the first rolling ball 216, the second rolling ball 43, and the pulley 53 is relatively parallel to the ground, which can ensure that the cutting knife 212 is perpendicular to the ground when moving down for cutting and avoid damage to the cutting knife 212. If the difference in the values measured by the distance measuring instruments 7 in the first telescopic column 41 and the second telescopic column 51 is large while the value measured by the distance measuring instrument 7 in the distance-adjusting telescopic column 213 is equal, it means that the cutting knife 212 is tilted forward or backward relative to the ground. At this time, the second steering motor 325 is started, and the longitudinal rotating column 324 drives the adjusting plate 323 to rotate relative to the fixed plate 326. The adjusting plate 323 drives the hydraulic telescopic column 31 and the shock-absorbing and temperature-reducing cutting assembly 2, the front baffle mechanism 4, and the water mist recovery mechanism 5 below it to rotate synchronously as a whole to adjust the angle in the overall front-rear direction until the values measured by the distance measuring instruments 7 in the first telescopic column 41 and the second telescopic column 51 are equal. If the difference in the values measured by the distance measuring instruments 7 in the symmetric distance-adjusting telescopic columns 213 is large, it means that the cutting knife 212 is tilted in the left-right direction relative to the ground. At this time, the first steering motor 322 is started, and the transverse rotating column 321 drives the hydraulic telescopic column 31 to rotate relative to the adjusting plate 323 to adjust the angle of the shock-absorbing and temperature-reducing cutting assembly 2, the front baffle mechanism 4, and the water mist recovery mechanism 5 as a whole in the left-right direction until the values measured by the distance measuring instruments 7 in the symmetric distance-adjusting telescopic columns 213 are equal. The relative angles of the shock-absorbing and temperature-reducing cutting assembly 2 as a whole in the left-right direction and the front-rear direction with respect to the ground are respectively adjusted by the first steering motor 322 and the second steering motor 325 to ensure that the cutting knife 212 is perpendicular to the ground when moving down.

[0031] After adjusting the relative position of the cutting tool 212 and the ground, start the power motor 232. At the same time, the first pumping pump 223 and the second pumping pump 224 work. The power motor 232 drives the cutting tool 212 to rotate. The second pumping pump 224 directly pumps the water in the water tank 221 into the water collection chamber 218 on one side. The first pumping pump 223 pumps the water in the water tank 221 into the power housing 231 through the connecting pipe 222, and cools it by water cooling when the power motor 232 is working. The water flowing through the power housing 231 flows into the water collection chamber 218 on the other side through the water pipe. The water in the water collection chambers 218 on both sides of the cutting tool 212 is sprayed out through the water spray nozzles 217 to cool the cutting tool 212 and play a role in dust reduction at the same time. The heat generated by the power motor 232 during operation is conducted away by the flowing water. The clamping plate 233 clamps the power motor 232, and the vibration generated by the power motor 232 during operation is offset through the shock-absorbing spring 234. In addition, under the enclosure of the power housing 231 and the water flow, the noise generated by the power motor 232 during operation is difficult to conduct out, playing a role in noise reduction. Start the hydraulic telescopic column 31. The hydraulic telescopic column 31 pushes the shock-absorbing and cooling type cutting assembly 2 to move downward as a whole. The distance-adjusting telescopic column 213, the first telescopic column 41, and the second telescopic column 51 contract, and the elastic compression spring 6 is compressed. When the contraction distance of the distance-adjusting telescopic column 213 is equal to the distance from the lower end face of the first ball 216 to the lower end face of the mudguard 214, that is, when the value detected by the rangefinder 7 is equal to its initial value minus the current contraction amount of the distance-adjusting telescopic column 213, the cutting tool 212 contacts the road surface. The hydraulic telescopic column 31 continues to push the cutting tool 212 to cut the road, and the cutting depth of the cutting tool 212 can be adjusted through the values detected by the hydraulic telescopic column 31 and the rangefinder 7.

[0032] The driving motor starts, and the rotating shaft 332 drives the toggle plate 333 to rotate. When the toggle plate 333 rotates, it forms an engaging transmission structure with the driving rod 16, thereby causing the driving block 331 to slide within the driving groove 15 and the bearing column 327 to slide within the sliding groove 14. At this time, the cutting blade 212 cuts the road. During this process, stones or debris on the advancing path of the cutting blade 212 are blocked by the front baffle 44 and slide along the surface of the arrow-shaped front baffle 44 to its outside, preventing the cutting blade 212 from touching the debris on the ground and being damaged. At the same time, the recycling basket 52 always stays close to the ground, and the water mist and mud splashed by the cutting blade 212 are sputtered into the recycling basket 52. Large-particle sludge impurities are collected by the stacking cavity 54, and the water in the water mist and sludge is adsorbed by the first filter cotton 511 through the mud filtering net 57. As the cutting operation progresses, the first filter cotton 511 adsorbs more and more water. After the power motor 232 works for a certain period of time, the timing control module of the main controller starts the conversion motor 59 and the third pump 225. The conversion motor 59 rotates the conversion screw column 58, thereby causing the conversion plate 510 to slide within the adsorption cavity 55. The conversion plate 510 slides towards the first filter cotton 511 and squeezes the first filter cotton 511 to squeeze out the water in it. The second filter cotton 512 unfolds under the drive of the conversion plate 510 and continuously adsorbs the water mist sputtered by the cutting blade 212. The water squeezed out from the first filter cotton 511 falls into the recycling cavity 56 through the water leakage net 513 and is then pumped into the water tank 221 by the third pump 225 through the suction pipe 226 for recycling. By sliding the conversion plate 510, the first filter cotton 511 and the second filter cotton 512 alternate in absorbing and draining water, extending the water filling cycle of the water tank 221, increasing the running time of the cutting blade 212, and improving the efficiency of the road cutting operation.

[0033] When there are multiple slope roads within the road range covered by the guiding mechanism 1, during the process of the cutting blade 212 advancing, the first ball 216, the second ball 43, and the pulley 53 around it are always in contact with the ground under the elastic pressure of the elastic compression spring 6. When a slope road appears, the difference in the values detected by the distance measuring instruments 7 within the first telescopic column 41, the second telescopic column 51, and the distance adjusting telescopic column 213 exceeds the threshold value, and the hydraulic telescopic column 31 immediately contracts, causing the cutting blade 212 to leave the ground. According to the above adjustment principle, the first steering motor 322 and the second steering motor 325 are used to respectively adjust the relative angles of the overall shock-absorbing and temperature-reducing cutting assembly 2 with respect to the ground in the left-right direction and the front-back direction, ensuring that the cutting blade 212 is perpendicular to the ground when it moves downward before performing the road cutting operation, preventing damage to the cutting blade 212, and improving the adaptability of the cutting device to complex terrains.

[0034] After the road cutting operation is completed, the hydraulic telescopic column 31 contracts and resets, the power motor 232 and the drive motor stop, the first suction pump 223, the second suction pump 224, the third suction pump 225 and the conversion motor 59 stop working. The staff cleans the mud in the debris chamber 54 and regularly cleans and replaces the mud filter screen 57, the first filter cotton 511 and the second filter cotton 512.

[0035] It should be noted that the water tank 221 is made of plastic material, so that the staff can see the liquid level height in the water tank 221, and then can replenish water to the water tank 221 in time. In addition, the forward direction of the cutting tool 212 is defined as the front side, which will not be elaborated here.

[0036] The above is the overall working process of the present invention. Just repeat these steps the next time it is used.
